My previous version had a minor bug in admin_role where it was using cobblerd_var_log_t, and cobblerd_var_lib_t instead of cobbler_var_log_t, and cobbler_var_lib_t.
Whilst i was at it, i decided the implement a cobbler_etc_t for cobbler content in /etc. This because you cannot admin a cobbler environment witouth having access to cobbler config files and i dont want to give cobbler_admin access to manage etc_t.
As a consequence if this i also removed the files_read_etc_files(cobblerd_t), as i think that cobbler only needed it to read its own files in /etc. However this is not confirmed, and it may need read access to etc_t afteral.
Also i would like to underscore my reason for using public_content_rw_t. One of the reasons is that i do not want to give cobbler access to manage httpd_sys_content_rw_t. In general i do not want to depend on apache module at all.

This one makes an effort to check for syntax and that it actually compiles.

The motivation for this was xdm_t objects not getting cleaned up,
so the user session tried to interact with them. But since the
default user type is unconfined this problem has gone away for now.

X Object Manager policy revisions to xserver.if.
This commit consists of two parts:
1. Revisions to xserver_object_types_template and
xserver_common_x_domain_template. This reflects the dropping
of many of the specific event, extension, and property types.
2. New interfaces:
xserver_manage_core_devices: Gives control over core mouse/keyboard.
xserver_unprotected: Allows all clients to access a domain's X objects.
Modified interfaces:
xserver_unconfined: Added x_domain typeattribute statement.

X Object Manager policy revisions to xserver.te.
This commit consists of three main parts:
1. Code movement. There were X object manager-related statements
scattered somewhat throughout the file; these have been consolidated,
which resulted in some other statements moving (e.g. iceauth_t).
2. Type changes. Many of the specific event, extension, and property
types have been dropped for the time being. The rootwindow_t and
remote_xclient_t types have been renamed, and a root_xcolormap_t
type has been (re-)added. This is for naming consistency.
An "xserver_unprotected" alias has been added for use in labeling
clients whose resources should be globally accessible (e.g. xdm_t).
3. Policy changes. These are mostly related to devices, which now have
separate x_keyboard and x_pointer classes. The "Hacks" section
has been cleaned up, and various other classes have had the default
permissions tweaked.

This is needed to allow more fine-grained control over X devices without
using different types. Using different types is problematic because
devices act as subjects in the X Flask implementation, and subjects
cannot be labeled through a type transition (since the output role is
hardcoded to object_r).

Hello
This a patch for adding xscreensaver policy.
I think it need a specific policy because of the auth_domtrans_chk_passwd.

The nscd policy module uses the old nscd cache location. The cache location
changed with glibc 2.7-1, and the current nscd does place the files in
/var/cache/nscd/.

Add policy for the new TUN driver access controls which allow policy to
control which domains have the ability to create and attach to TUN/TAP
devices. The policy rules for creating and attaching to a device are as
shown below:
# create a new device
allow domain_t self:tun_socket { create };
# attach to a persistent device (created by tunlbl_t)
allow domain_t tunlbl_t:tun_socket { relabelfrom };
allow domain_t self:tun_socket { relabelto };

Add the new "tun_socket" class to the flask definitions. The "tun_socket"
object class is used by the new TUN driver hooks which allow policy to control
access to TUN/TAP devices.

The X policy for users is currently split between
userdom_xwindows_client_template() and xserver_role(). Deprecate
the former and put the rules into the latter.
For preserving restricted X roles (xguest), divide the rules
into xserver_restricted_role() and xserver_role().
The unconfined role is running java in the unconfined_java_t. The current
policy only has a domtrans interface, so the unconfined_java_t domain is not
added to unconfined_r. Add a run interface and change the unconfined module
to use this new interface.

Unconfined_cronjob_t is not a valid cron job domain because the cron
module is lacking a transition from the crond to the unconfined_cronjob_t
domain. This adds the transition and also a constraints exemption since
part of the transition is also a seuser and role change typically.

Making it systemhigh will generate lots of AVC messages on every login
at X Since fusefs is mounted at ~/.gfs. It will also make it unusable I
believe on an MLS machine. Mostly I have seen fusefs used for remote
access to data. sshfs for example.
